Patented Aug. 2l, l

To all whom it may concern.-

Be it known that I, DAvID A. Pon, residing in the city of Montreal, in the Province of Quebec, Dominion oi Canada, have invented a new and useful Improvement in Linotype Machines, of which the following is a specilicatioii. v

My invention relates to linotype-machines wherein circulating matrices, composed in line together with expanding wedge spacers, are presented 'temporarily in iront of a slotted mold to form type characters in relief on a slug or linotype cast in the mold.

t relates more particularly to the machine represented in Letters Patent of the United States No. 734,746, to Poe t Scharf, dated July 28, 1903, wherein the composed linefof matrices is -advanced in a continuous path from the movable supporting devices to a position infront of the mold and thence to the carriers, which deliver them to the distributing mechanism; andit consists in improved means for confining or clamping the line of matrices endwise in iront ofthe ino-ld.

In the original machine a line was presented in front of the mold carrying rigid jaws or projections at its ends, and the advancing of the mold toward the matrices caused its jaws 'to embrace the line, which was thereafter eX- panded lengthwise between the jaws by the adjustment of the spacers or justiiiers. This method1 of confining the line is open to various objections, which l now overcome by the employment or movable jaws or clamps separate ironi the niold and arranged to corinne the line when in the casting position, as here- 'inaiter described..

With the exception of the parts specifically described and claimed herein the machine maybe in all respects like that re resented in the patent or ot any other siiitab e construc tion. In, the drawindgis l have shown only those parts which are rectly associated with my improvements.

Figure 1 is a vertical cross-section through' the mold, matrirnsup ort, and clamping de vices on the line 1 ig. 2. Fig. 2 is a top plan view of said parte, portions bein@r shown iii section. y

Referring .to the drawings, 'A represents the main frame. H is the slotted mold, se-1 cured inthe arm i, which is mounted to os- .eillate aroiind horizontal and also arA ranged to move in an axial direction to and from the line of matrices.

G is a slotted line support or yoke in which the composed line of matrices Yand wedge spacers Z is sustained in iront of the mold during the casting operation.. The matrixline is moved eridwise horizontally into the support G through its front end and remains in the sup iort during the casting operation,

after Whic i it is moved horizontally out of the support at the rear end of tlier'latter toward the distributing mechanism.

It will be observed as a characteristic feature of the foregoing mechanism that the matrixdine is advanced intermittingly along a straight or continuous path first from the usual preliminary support into the support G through the forward end of the latter and finally out of the rear end of the support G to the lifting devices.

The foregoing parts may all be constructed and arranged to operate in the same or essentially the same manner as the parts indicated by like 'letters in the original patent, except that the mold is to be made, as shown,with` out the end projections or jaws to confine the matrix-line.

For the purpose of confining the line l now provide twoclamping jaws or arms U U, which may be formed and'mounted in anyT manner that will admit of their being advanced to embrace the iilatriX-line While itis sustained in the support G and of their being subsequently retracted from the, path of the matrices that the latter may continne their course rearward ont oi the support. jaws are preferably made, as shown, with arms mounted on a roclnshaft u, which .is sustained in the main frame and provided with a crank-arm a', connected by links u with the usual mold-operating cam or other source oli motion. The-parts are so timed 'that after the matrix-line has arrived at the driven upward through'the line in the usual The manner. Alter the casting action the ,iaws

zo endv ise from the support G. i ing action expands the hnetignti eetwecn again tali, leaving the line i'ree to moved nstiicy'-l i the jaws U U, it is desirable to relieve the pressure in order to permit easy downward movement of the jaws. To this end I connect the arm U to the supporting-shaft u by a spline or key a4, seated in a longitudinal slot a5 in the shaft, so that the distanceb'etween the larms may be varied. Upon or against the outer side of the arm U, I arrange a nut u, held normally against rotation around theshaft. Within this nut I mount a threaded sleeve a7, provided with pinions u8, which engage a second pinion a on a shaft al", mounted in the main frame and provided with a crank-arm u, connected by a link uw with any suitable moving part of the machine. The parts are so timed as to turn the threaded sleeve a7 and move the'j aw U toward its companion U after they have risen to embrace the matrix-line and, on the other hand, to reverse the motion of the sleeve and separate thejaws after the casting action and immediateljy before the jaws are lowered from the line. By turning the nut a in relation to the arm U the working distance between the two arms may be varied to suit the different lengths of the line which the mold of the machine may be adapted from time to time to produce.' The nut may be secured in relation to the arm U by a lockingslide um, secured by a nut u or by any other suitable means. A spring 11,15 is preferably mounted between the jaws around the shaft 'alto force the jaws apart when they are released. In order to give additional rigidity to the jaws when in action, they may be arranged to interlock with the mold in any suitable manner.

In the drawings I have shown the mold as provided at the leftI end with a projection h', adapted to enter a' notch in the end of the jaw. At the right end of the mold I have shown a ca'vity h2, adapted to receive a projection on the end of the jaw. By thus interocking the jaw and the mold the separation of the jaws. is prevented when the'line is forcibly expanded between them. As the molds are commonly constructed the right end of the slot is closed by a movable liner or plate, which may be adjusted or replaced by .5o

erative position after the matrix-line is in the castin position. I also believe the present to be t e first instance in which the mold and the composed matrix-line' have been combined with line-confinin jaws or abutments adapted to interlock wit the mold.

szaeso spacers are driven upward through the line to effect its justification, the mouth of the pot K being closed against the back of themold and the latter filled with molten metal from' the pot, as usual. The` pot and mold then retreat. The jaws are retracted from the ends of the line and the line carried out to the rear end of the support G toward the distributing mechanism.

Having described my invention, whatI claim isy l. Inalinotype-machine, the combination of a mold, a matrix-supporting yoke locatedV adjacent to the mold and open at both ends to permit the entrance of the matrix-line at. one end and its delivery at the oppositeend,

in combination with line-confining jaws,

means for advancing the .jaws into and retracting them from the path of the matrices, and means for approximating and separating the jaws.

2. In a linotype-machine of the characterv described, a mold, a horizontally-slotted matriXesupport open at the forward end to admit the line of matrices and also open at the Arear end to permit the escape of the matrix-` line,two matrix-confining jaws, andv means for advancing these jaws into the slot of the support to confine the matrices before the mold, and means for retracting the jaws beyond the path of the matrices.

3. In a linotype-machine, a mold, a horizontal slotted support adapted to sustain the line of matrices and spacers in front of the mold, said support open at both ends that thematrices may enter at one end and escape at the other, two matriX-connino' jaws pivoted to swinginto and out of the matrixath. v p 4. In a linotype-machine, the combination of a slotted mold and line-confining -jaws arration of the jaws line is prevented. l

5.` In a linotype-machine, the combination of a mold, line-confining jaws adaptedto interlock with the mold and confine the line in during justification of the 4casting position, and means for moving the IOO IIO

ranged to interlock therewith, whereby sepa- Y with the mold', a matriX-support'-7 the rockshaft, the fixed jaw -U and movable jaw U mounted on said shaft and arranved to confine the matrices before the moll, a spring tending to separate said jaws, a screw for approxmating the jaws, and automatic means for actuating the screw; 4

/ 8. In a linotype-machine, the combination of .a mold, means for sustaining the matrixline infront of the mold, and two verticallyswinging jaws adapted to confine the matrix- Aline between them. A

9. In a linotype-machine and in combination with the mold and coperating matrices, a horizontal matrix-support open at both ends that the matrix-line may be carried therethrough, two matrix-confining jaws,

and means for moving the jaws vertically into the Slotted support to confine the matrices therein and foi' retraeting them beyond the path of the matrices that the'latter may enter and leave the support. Y In testimony whereof I hereunto hand, this 5th day of March, 1906, inthe presence of two attesting witnesses. v
